Never had a problem with my 242 on the KJ.

Hasn't stuck nor has it ever let me down.

From what Ive read, ATF+4 is straight 30w but idk if theres any truth to that. Someone posted it on JU.

When hot, it's a 20 wt. Due to it's excellent cold temp properties, I'm guessing it would be like a 5W20.

Nope, I was referring to the original Quadra trac used in FSJ's through 1979. It was a Borg Warner T-case ( BW 1335?) and had to use AMC Q-trac fluid unless you put a part-time kit in it. But the 247 is probably anothe fine example of "you better run what they tell ya." T-cases seem to be a prime example of the KISS principle. If you don't KISS, you get more headaches.

wow, thats way before my time!

I have been running ATF+4 in my 242. I have not had any problem with the 242 and I use it a lot. I think I will leave mine alone. I thought the ATF+4 was a synthetic ????

The Mopar ATF+4 is a synthetic. But like all synthetics, the quality is different. The Mopar ATF+4 is pretty good stuff, however it does break down quicker. The Amsoil ATF has a better additive package, comes from a better base stock ( better grade of synthetic) and will last longer under higher stresses of heat. If I were you, I would change my transmission and transfer case fluid much sooner than what the owners manual recommends. HEAT is the main destroyer in most working components.

My best shot at "guess that T-case" without looking anything up

Sport - 231,242,241
Renegade -231,242,241
Limited - 231,242

Auto 231 or 242
Manual -5spd=231 6spd=241

4 Cyl 231 & maybe 242
6 Cyl 231,242, 241
CRD 242

2002 231 or 242
2003-04 231 or 242
2005-07 231, 242, 241

231 is the command trac (part-time) and the 242 is the select-trac (full-time)

the 231 doesn't suck! Teehee

Seriously, though, the 242 has a center differential to allow 4wd to be engaged on dry pavement, and that center diff also locks in 4hi.
